Music Device Equipped with Image Display

Abstract

A music device includes a characteristic extraction means 103 for extracting two or more characteristics included in music information from this music information, image generating means 105 to 111 each for generating an image which has variations which differ dependently upon each of the two or more characteristics extracted by the characteristic extraction means, and a monitor 112 for displaying the images generated by the image generating means.

1 . A music device equipped with an image display, characterized in that said device comprises:
 a characteristic extraction means for extracting two or more characteristics included in music information which defines music from said music information;   an image generating means for generating an image which has variations which differ dependently upon each of the two or more characteristics extracted by said characteristic extraction means; and   a monitor for displaying the image generated by said image generating means.   
     
     
         2 . The music device equipped with an image display according to  claim 1 , characterized in that the characteristic extraction means comprises a Fourier transform means for calculating at least two of a plurality of frequency components included in music information, and amplitudes and phases of the plurality of frequency components by performing a Fourier transform on the music information, and the image generating means generates an image which has variations which differ dependently upon at least the two of the plurality of frequency components, and the amplitudes and phases of the plurality of frequency components, which are calculated by said Fourier transform means. 
     
     
         3 . The music device equipped with an image display according to  claim 2 , characterized in that the image generating means generates the image showing an animation character. 
     
     
         4 . The music device equipped with an image display according to  claim 3 , characterized in that the image generating means comprises a character drawing rule defining means for associating parts of the character with the plurality of frequency components acquired by the Fourier transform means, respectively, and for determining a representation of each of the parts of said character according to an amplitude level of each of the plurality of frequency components, an inside-of-character drawing means for processing parts to be drawn on a basis of the representation determined by said character drawing rule defining means, and for outputting the parts to be drawn as parts-to-be-drawn information, and a drawing means for drawing the character on a basis of the parts-to-be-drawn information sent from said inside-of-character drawing means, and for outputting the character to the monitor. 
     
     
         5 . The music device equipped with an image display according to  claim 4 , characterized in that the image generating means comprises an increase-or-decrease rule defining means for defining a rule which is used to set up an increase-or-decrease parameter for controlling a number of characters displayed on the monitor according to an amount of change with time in each of the plurality of frequency components acquired by the Fourier transform means, and a character number increase-or-decrease judgment means for controlling increase or decrease in the number of characters displayed on the monitor according to the increase-or-decrease parameter controlled according to the rule defined by said increase-or-decrease rule defining means.
